NEW DELHI—One of India's foremost anticorruption crusaders was sworn in Saturday as the chief minister of Delhi after an electoral debut that has shaken the Indian political establishment.

Arvind Kejriwal's Aam Aadmi, or Common Man, Party was born just one year ago out of India's anticorruption movement, which brought tens of thousands of middle-class Indians to the streets to protest endemic official graft.
